Seed guide device and seeding monomer with same

Abstract

The invention discloses a seed guide device and a seeding monomer with the same. The seeding monomer comprises a rack, power and transmission devices, a covering device, a ditching device and a seeding system, which are arranged on the rack; the power and transmission devices are connected with the seeding system; the seeding system comprises a seed box, a seeding apparatus and a seed guide device; the seed box is arranged above the rack; the seeding apparatus is arranged below the seed box and connected with a seed charge port of the seed box; the seed guide device is arranged below the seeding apparatus; the seed guide device comprises a seed pipe, a seed guide mechanism and a transmission mechanism; the seed pipe is of a closed barrel structure; openings are respectively formed in the upper end and the lower end of the seed pipe; the seed pipe comprises a linear control section and a curve seed guide section, which are sequentially connected; the opening at the upper end of the seed pipe is formed in the linear control section correspondingly to the seed charge port of the seeding apparatus; the direction of the opening at the lower end of the seed pipe is reverse to the advancing direction of a seeder; and the seed guide mechanism is arranged inside the seed pipe correspondingly to the seed charge port and connected with the transmission mechanism.

Description

technical field [0001] The invention relates to an agricultural seeding device, in particular to a seed guiding device which is used for seeding with a precision seed metering device and can eliminate bouncing, make the seeds relatively fixed, and improve the uniformity of the particle distance and the accuracy of the landing point of the precision seeding And the sowing unit with the device. Background technique [0002] In the prior art, the seeding height of the seeder (the distance from the seeding opening to the bottom of the seed ditch) has a great influence on the distribution of seeds falling into the seed ditch. Due to the limitation of the structure of the working parts of the machine or the working principle of the seed metering device, it is impossible to reduce the seeding height very low, especially for the precision seeding unit of the double disc opener of large machines, the distance from the seeding port of the seed metering device to the bottom of the ditc...

AI Technical Summary

Problems solved by technology

The higher the seeding height, the longer the distance the seeds have traveled, the greater the interference they will receive, and the easier it is to cause inaccurate seed placement

[0003] The application number is "02292089.7", and the Chinese utility model patent titled "New Soybean Intertillage, Spraying, Precision Zero-speed Seeder" discloses a precision zero-speed seeder that realizes equal plant spacing. Seeds falling from the seeding port of the device, the seeds are relatively fixed in the groove of the seeding rubber plate, and the seeding rubber plate is connected with the sliding knife ditch opener, so that the seeds are dropped into the soil that the sliding knife slides away, but the involved throwing The seeding device is a circular structure, and this mechanism is only suitable for a specific sliding knife opener, and its application is subject to certain restrictions
